SPECIFICATION forming part of Letters Patent No. 288,422, dated November 13, 1883.

Application led September 11, 1853.

(No model.)

To LZ whom t may concern:

Be it known that I, LoUIs GoDDU, of Winchester, county of Middlesex, State of Massachusetts, have invented an Improvement in Failing-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention is an improvement on the 1o machine represented in United States Letters Patent No. 265,227, granted to me September 26, 1882, and has chiefly to do with the apparatus for separating the headed nails or iastenings singly from the roadways and transferring them into line with the driver-passage. In this invention I employ both a separator and a transfcrrer in connection with each roadway of the chute, the separator first operating to enter between two nails, while the transfer- 2o rer closes the end of the roadway, and, having been entered between the nail next to be driven and the one next back of it, the transferrer is moved away from the end of the chute, permitting the separator, in its further forward movement across the roadway, to push the nail next its beveled face off the end of the said chute directly in front of the end of the transferrer, so that the latter, as it next comes forward, will strike the said nail and move it into 3o the driver-passage, which passage is located just where the end of the transferrer stops when it is in its position to fully close the end of the roadway from which it took its nail. Before the transferrer is drawn back from its 3 5 forward position to take another nail, the separator is drawn fully back and again started forward far enough to enter its point between the endmost nail and the one neXt to it, thus making it impossible for the nails to come tol 4o gether between the separator and transferrer.

The transferrer not then active, but closing the roadway from which nails are not at the time being taken, remains at rest at the end of the said chute and roadway, and the end of 4 5 the said transferrer remains at rest at the driver-passage.

Figure 1 is a detail showing parts of the patented machine referred to with my improve ments added. Fig. 2 is an enlarged view, looking at Fig. 1 from the left of the section- 5o line x as, some of the parts being, however, broken out, some parts in duplicate being also shown in dotted lines. Fig. 3 is a section of Fig. 2 along the dotted line m2, Fig. 2. Fig. 4c

is a detail showing the end of the chute, its roadways, the separators, transferrers, and driver-passage.

In the drawings, the vibrating head B, driver-bar a, the nail-receiving drum E, the chute m, the stops]3 f, sector f5, tube f8, spring- 6o pressed pin f l therein, throat c, shaft C, cover a, and joint at h are all as in my said patent, and need not therefore be herein further particularly described.

The part f8, turned to the right or left be 65 fore changing from one to another length of nail, compresses the spring in the said tube against the pin fl, and stores up power sufcient to turn the sector f5 and move the stops as soon as the cams for moving the levers o o 7o turn the same far enough to permit the said levers to pass beyond the ends ofthe said stops, as fully described in the said patent and in my application, Case A, No. 106,133, filed concurrently with this.

The chute m has two roadways, 2 3, and a suitable cover, a5. The divisionwall between the roadways presents a vertical ilat end, which, at a point intermediate the ends of the said roadway, has in it part of the driver-pas- 8o sage u, which is in continuation of the driverpassage u2, above the nose c. In connection with the roadway 2 is a separator, a, attached to the lower end of a lever, b, having a sleevehub which surrounds a stud, d, the said sleeve 8 5 having a second arm provided with a roller,

c, which is acted upon at suitable times or intermittingly by a cam, g, forming part of a sleeve, 7L, fast on the shaft C and partaking of its movements. The roller c is kept against 9o the cam g by a spring, i, which at its other end is connected with a pin on a lever, b', (shown in dotted lines, Fig. 2,)like b.

One face of the separator is beveled, as shown in Fig. 4, and at its side is a transferrer, a, attached to a lever, o, (see Fig. 1,) having a solid or fast stud, d, which is extendedV through bearing-passages made in the head B,

the end of the said stud so extended through the head having fastened to it an arm, p, (see Fig. 4,) which is attached to a corresponding arm, p', by means of a spring, q, the arm p being attached to a stud, d', having fast on it Ythe lever o', which carries the trausferrer n,

Ywhich (zo-operates with the roadway 3. rIhe studs d d are prolonged at the outer sides of the levers o o, to forni studs for the reception of the two like levers, b b', having arms provided, respectively, with rolls e e', to be acted upon nby the cams g g', both alike Von the sleeve h.

The lever b has a separator, a, which cooperates with it and roadway 3. In Fig. 2, I have shown the lever b' by dotted lines.

Each lever o 0 has a roller-stud, r, which is adapted to be acted upon at desired times by one of the cam-faces s or s of the sleeve h.'

It will be understood that the partsb b', Snc., marked by like letters without and with the prime mark, are in operation just the same, the only difference being that one set works with one roadway, 2, and the other with the other roadway, 3.

lIhe nose e has an awl-passage, i, and a driver-passage, a3, and is bolted to the head B by a bolt at 8. The transferrer is slotted at its ends.

I claim- 1. The chute provided with the two roadways, and the nose having the driver-passage, combined with the two separators, to act upon and separate the endmost nails ofthe series of nails from those next back of them, and the transferrers to take the said nails and transfer them at the proper times in opposite directions toward and to the driverpassage, substantially as described.

2.. The ehuteiprovided with the two roadways, and the nose having the driver-passage, combined with the two separators, to act upon and separate the endmost nails of the series of nails from those next back of them, and the tra'nsferrers to take the said nails and transfer them at the proper times in opposite directions toward and to the driverpassage, and with means, substantially as described, to enable the operator to control the selection of nails from one or the other of the said roadways. Y

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
